“He had very good results,” Carroll told 710 ESPN Seattle radio hosts Brock Huard and Danny O’Neil on Monday morning. “He had some stuff in his knee that was causing him some problems that they cleaned up. He could make a very quick recovery on that one.”

“He had loose bodies — did not have a lot of damage other than that,” Carroll added. “So that’s really encouraging, because they clean that stuff out and it’s just like it wasn’t there. So we’ll hopefully get him back quickly.”

Giacomini, 28, left the Jacksonville game Sept. 22 after his already sore knee flared up. He missed practice all of last week and was inactive for Sunday’s game in Houston.

The Seahawks were without three starters on the offensive line Sunday — Giacomini, left tackle Russell Okung and center Max Unger — and it showed. Russell Wilson and the Hawks offense couldn’t get anything going against the blitzing Texans for the better part of three quarters, only to surge back in the fourth quarter and force overtime once Wilson put the team on his back.

Rookie Michael Bowie started in Giacomini’s place, and backup Lemuel Jeanpierre stepped into Unger’s spot. To account for Okung, who is on the injured reserve for six more weeks with a toe injury, the Seahawks slid left guard Paul McQuistan over to tackle and started James Carpenter at left guard.

The fact Seattle pulled off the 23-20 overtime victory, with three starters missing from the O-line and against Houston’s hard-hitting pass-rush, is nothing short of incredible.

“Well, we made it, we survived,” Carroll said on 710. “I thought Lem (Jeanpierre) played particularly well; he did a good job in the middle. Michael (Bowie) had his moments where he did some really good things, and then he struggled at times. And Paul (McQuistan) had issues on that left side, over there — (the Texans) were roaring off the edge, too.

“So, we survived it, basically, and got through the game, and we’ll be better for it. I think it’s an enormous accomplishment to face it that way. And I’m proud of that — really proud that those guys could pull it off, get a win and get out of there. Because we’ll be stronger, we’ll be better because of this.”

Meanwhile, Carroll said that Unger (arm) is “really excited about getting back and feeling pretty good.” The Seahawks will see how much their All-Pro center can practice this week before the team heads to Indianapolis next weekend.
